Well Kim you were faced with quite a dilemma and you chose to tell your friend about it, apparently it has been the right decision, so be comfortable in knowing that, it does not always turn out that way, and I guess I would probably not have said anything, although i certainly would have wanted to, you can only do what you think is right, I once was faced with a very awkward situation, my then best friends husband flirted with me behind my friends back, and on the phone, it used to upset me terribly, he would tell me how he thought i was nice looking and all that kinda of stuff, i wanted to tell her desperately but i never did, i think it was the right decision in this particular case, now years on she divorced the creep and knows what he is really like, but still i would not tell her even to this day, some things are just best left unsaid.,in my case anyhow.
